Pi amibroker bridge guide

Hello

I am not from a coding back ground so its bit confusing for me

I have an AFL with buy sell Short cover signals

I want to trade on this so i took PI bridge.
Yesterday somebody from support enabled it by running some AFL but today again its in RED

I want to know how to enable it again
and also how does it generate alerts in PI

Yesterday no alerts got generated in PI but I could see the buy sell short cover signals in AFL charts

Suppose I have AFL running on say 3

1.Nickel
2. Nifty future
3. USDINR future

and all of them are in market watch of PI so what should I do to get alerts for me to trade in PI

Can u please guide on phone so I can start my trading
